IMPROVEMENT IN COUPLING- PQR VHICLES. I l

The Schedule referred to in these Letters Patent andmiaking part o! the same.

To all whom fit may concern: i

Beit known that I, UPsoN AIBUsHNnLL, of Cleveland, in the county of Cuyahoga, and in the State of Ohio, have invented certain new and useful Improvements in Couplings for Vehicles; Aand do hereby declare that the following is a full, clear, and exact, description thereof, reference "being had to the accompanying drawings, and to the letters ofreference marked thereon, making a part of this specification.

The nature of my invention consists in the cou-l struction aud arrangement of a coupling for vehicles, having rits centre and kingboltroutside of lthe axle and head-block, and dispensing with the usual circle, or ifth-wheel.- y

-In order to enable others skilled in the art to. which my invention appertains, tomake and use the salue, I will now proceed to describe its construction and operation, referring to tlreanuexed drawings, which rep- 'resent a longitudinal vertical section of myconpling.

A represents the axle, to the front sideof which the .lower male section B,4 of the joint, is firmly secured,

by bolts and cap-plate. l

The cap-plate C is 'secured by .bolts to the bottom of the', axle A, and project-s forward in the centre far enough to form a cap for the lower end of the lower ,section B of the joint, and also toreceilve and supportv the lower end of the king-.bolt D.

The upper or female section, E, of the joint, is secured to the head-block G and springs H H, by bolts and a cap, I, secured by bolts on the top of the springs H H, to support the upper' end ofjoint-and king-bolt,

i the same as the cap G does the bottom.'

The inside' of the joint is formed with one or. more bevel elevations, a, soformed as to be bevel-shaped upon both sides', .so that as it bears, it always lits and makes the joint self-tightening.

The oil-chambers are formed by an enlargement in the lower part ofthe upper section E, and grooves in `the top part of the lower` section.

llhechamber inthe upper section is accessible by means of a hole in the upper section, where the packing or oil-retainer and oil can be introduced, to be se'- cured from dirt by a cap* or top screw; This makes it self-lubricating.

rlhe upper section E entirely caps over the'lower section, makingit self-protecting fronrall dirt. n

'lhe king-bolt D is provided with screw-threads upon the upper end, and passes through a screw'cut iu the upper part of the upper section E, soas to bring thejoiuttoa perfect fit, thereby rendering itl noiseless. It is also secured at the top by achecknut, J, which 'holds it to its place.

The lower end or king-bolt 'head rests upon the brace K, from the bottom of the reach L,ar1d.passes. loosely through the lower section B of the joint. This avoids all friction upon-the bolt, and permits the axle to self-adjust itself upon its two points of bearing.

Having thus fully described my invention,

p What I claim as new, and desire to secure by Lette-rs Patent, 4is l j 1. The bevel-shaped joint BE', constructed. as. de-l scribed, so as'to give the head-block and axle a bearing upon the joint with its centre and king-boltoutside of said axle and head-block, substantially as herein set forth. l

'2. The mannerof oiliug the joint B E, by having an enlargement or chamber in the lower portion of' theupper section, and grooves iu the top of the lower' section, substantially as herein set forth.

3. The combination and arrangement of the axle joint B E, cap-plates C I, head-block G, springs HH,

screw king-,bolt D, nut J, and brace K, all constructed as described, substantially as and for the purposes here- .l
